Abstract
A pressure sensing module for an electronic device includes a substrate and a module housing coupled to the substrate. The module housing defines a first chamber and a second chamber. The second chamber is separate from the first chamber. The first chamber is configured to connect to an environment around an electronic device. The second chamber is configured to connect to an internal volume of the housing of the electronic device. A first pressure sensing element is electrically coupled to the substrate and disposed in the first chamber and is operative to detect an external pressure around the electronic device. A second pressure sensing element is electrically coupled to the substrate and disposed in the second chamber and is operative to detect an internal pressure within the electronic device housing.
